Formatting of JS code breaks down after multiple newlines

[fatso83]

A picture speaks more than a thousand words.

This:

is the rendering of this code (from here):

it("should move in chunks of 100 steps per frame", async () => {
    clock = fakeTimers.install();
    const player = new Player();

    const movePromise = movePlayer(player, 300);

    assert.equal(player.x, 0);
    await clock.tickAsync(3*16);
    assert.equal(player.x, 300);

    return Promise.all([clock.runAllAsync(), movePromise])
});

Github renders this fine, but the 11ty plugin screws up the formatting between the lines and in front of them after a couple of lines.

I tried upgrading (from a really old version to the newest of all), to no avail. I guess this is what the "robustness" bits of #32 is about?
